Twilio has announced the general availability of its Voice Recording Encryption feature, which provides an additional layer of security for customer call recordings. This feature is designed to protect sensitive information in recordings, such as those used for training, compliance, and dispute resolution. With Voice Recording Encryption, businesses can control who accesses their recordings by using public and private keys, ensuring that only authorized individuals can listen to the contents of the recording. The feature is included with Twilio's Enterprise Edition, but for non-Enterprise customers, it costs $0.015 per minute of encrypted recording time. To get started, users must generate a key pair, submit their public key to Twilio, store their private key securely, enable the feature, and decrypt recordings using their private key.
